About our external mastic in Potterton
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. If you have hard, crazed mastic that has stopped moving and brick movement joints where the sealant has split, we can put it right.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
There’s a 12-month guarantee on every job.

Potterton buildings and the weather
Potterton is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Around Potterton, as everywhere, external mastic is only as good as the preparation behind it.

How the job changes by surface
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
The process
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. Outdoor work around Potterton depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Plan for the work area to be out of bounds to pets and children

- Any mould that needs treating
- How much there is to do
- How many areas need sealing

Common problems we fix in Potterton
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Any of these means the joints need attention:
- Sealant that has lost its bond to the brick or render
- Moss and dirt in joints with no sealant left
- Water getting into walls through failed joints
- Failed seals between different materials
Rented homes near Dyce station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

What else we do in Potterton
What we cannot put right
In fairness, there are a few things sealant won’t fix:
- Rising or penetrating damp from elsewhere in the wall
- Adding movement joints to masonry that has none
- Loose or hollow render, which needs re-rendering
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before booking.
Joints and surfaces we work on
- Brickwork movement joints
- Façade panels
- Copings & trims
- Joints between brick and frames
- Render & cladding joints
- Concrete & block
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
FAQs for Potterton
Can you help a landlord with a rental near Dyce station?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Does the coastal weather in Potterton affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Are you insured?
Yes. Full insurance covers our work.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces.
How do you reach high-level joints?
It depends on the building. Tell us the height, the number of joints and what’s below them.
Landlords, agents and businesses in Potterton
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
